Light Polarization as an Independent Measure of Atmospheric Purity and Transmittance

Abstract

The purity of the atmosphere is characterized by the quantity and size of the particles of dust and moisture (in liquid and solid phases) suspended in it. That the purity, or turbidity, of the atmosphere can be assessed from the polarizing properties of its gaseous and aerosol components is a point that does not meet with any fundamental objections. But the practical solution of this important problem involves great difficulties. And this explains the conflicting opinions that have been expressed in recent years by many researchers [1, 2].
